I've set up a multi-site network and all seemed ok. I am using sub-domains and I've created a couple of blogs at blog.mysite.com, so the basic structure seems to be working.
My problem is that whenever I try to install an mu-plugin, all the functions of the plugin seem to link to a blank page on my site. Specifically the plugins options that appear under 'Super Admin'.
Weird problem I know, but frustrating. What could I be doing wrong.
